A. Ignoring air drag, what is the takeoff speed of such a flea? (in m/s) B. Calculate the kinetic energy of this flea at takeoff (in J) C. Calculate the kinetic energy per kilogram of mass (in J/kg)
A. Ignoring air drag, what is the takeoff speed of such a flea? (in m/s)
B. Calculate the kinetic energy of this flea at takeoff (in J)
C. Calculate the kinetic energy per kilogram of mass (in J/kg)
D. If a 73.0 kg, 1.80 m tall human could jump to the same height compared with his length as the flea jumps compared with its length, how high could the human jump? (in m)
E. If a 73.0 kg, 1.80 m tall human could jump to the same height compared with his length as the flea jumps compared with its length, what takeoff speed would the man need? (in m/s)
F. Most humans can jump no more than 60.0 cm from a crouched start. What is the kinetic energy per kilogram of mass at takeoff for such a 73.0 kg person? (in J/kg)
